Abstract
Abstract A collapsible carriage frame has a front leg pivoted intermediate its ends to a tie bar which is also pivoted to one end of a side member which supports a basket-bassinet. The other end of the side-member is pivoted to a rear leg of the frame. Both the front and rear legs are pivoted to a handlebar which upon rotation relative to the front leg will fold the frame and position all the members of the frame so they are approximately parallel to one another.
